Out of the Blue
2006, True Life
A middle-aged loner becomes the perpetrator of New Zealand's largest mass murder when an argument between neighbors ends in a shooting. After killing his neighbor, David Gray (Matthew Sunderland) sets fire to the man's house with children inside, then shoots anyone else who wanders into range. Authorities are helpless to rescue the victims, and a long night begins as townspeople huddle in their homes as Gray rages on outside.
